A commission investigating a mass shooting that killed 18 people in Maine last year is scheduled to hear Thursday from a police agency that had contact with the shooter before he committed the killings.
Democratic Gov. Janet Mills and state Attorney General Aaron Frey assembled the commission to review the events that led up to the shootings at a bowling alley and a restaurant in Lewiston on Oct. 25. Commissioners, who are holding their second meeting Thursday, are also tasked with reviewing the police response and will speak to members of the Sagadahoc County Sheriff’s Department.
